What the difference between magnitude and direction?

A. Determine if p = 91-6j-24k and q=(-15,10,40) are parallel, orthogonal or neither. B. Determine the direction cosines and direction angles for D= (-3,-1/4,1)

Two ships, one sailing at 30mi/hand the other at 457mi/h, left port at the same time. Three hours later they were 120mi apart. If you had to find the angle between their courses, an equation that could be used to solve this problem is:

Dora, Boots and Swiper are camping. If Dora's tent is 155m from Boots' tent, Boots' tent is 200m from Swiper's tent, and Swiper's tent is 175m from Dora's tent, what are the angles between the tents?

a pilot must actually fly due west at a speed of 382 mph against a head wind of 55 mph blowing in the direct 22° south of east. What direction and speed must the pilot maintain to keep on course?

Question 2 (2 points) Directions: Find the value of X. Round your answe T 44 16 22 X3D Blank 1:

An old fashioned pirate ship departs from Pirate Island at a bearing of 30º. The ship  travels 30 km/h for 2 hours when it reaches Buccaneer Bay, where all of the treasure is buried. The ship drifts away from the bray for 4.5 hours at 12 km/h at an unknown bearing. While most of the pirates celebrate pirate things, the navigator wakes up from her nap and sees Pirate Island due East. The angle between the ship’s path and Pirate Island is 105.8º.   a. Find the bearing of the ship’s current location from Buccaneer Bay. b.Find the distance from the ship to Pirate Island.
